Abstract

The clay extruder includes a drum 2 having a screw 4 having a rotary shaft 6, a spiral rotary blade 5 for feeding the clay under pressure while kneading the clay fed into the screw, a pressure raising portion 10 to feed the clay under pressure while kneading the clay, and a rectifying portion 11 provided on the side of an extrusion port 20 in the drum 2 to rectify the clay into a columnar shape. The rectifying portion 11 has a rectifying rotary blade 7 whose intervals being longer than that of the rotary blade; an angle formed between the face on the side of the extrusion port in a sectional shape of the rectifying rotary blade cut along the central line of the rotary shaft 6 and the central line gradually decreases, as the rectifying rotary blade comes close to the extrusion port.
